Query context
Show the active search term and any correction or extension.
Result page
Make it clear why these results are shown.
A results page should make query, numbers, filters, sorting and product choice understandable without flooding the visitor.
Result number
Use numbers as context, not as the main message.
Sorting
Make relevance the safe standard and make alternative sorting options understandable.
Filters
Only show facets that have value in the current context.
Product cards
Show features that help choose, not just decoration.
Reformulate
Make customization of the query easy without leaving the page.
